CLOTHES-WASHING momma.

Application filed January 1, 1920. Serial No. 855,515.

T 0 all whom it may] concern Be it known that JOHN N. Dnnsonno, of Syracuse, in the county of Onondaga, in the State of New York, has invented new and 5 useful Improvements in Clothes-Washing Machines, of which the following, taken in connection with the accompanymg -draw ings, is a full, clear, and exact description.

This invention relates to certain improve- 19 ments in clothes washing machines involving the use of a suitable 'vat adaptedto contain the washing fluid and articles to be washed, cup-shaped dashers mounted upon-a; vertical reciprocatary plunger, which is movable through a central opening in-the bottom at the yet, a wi'in er for feeding the clothes-into and but of tie vat, a motor 'mounted upon the supporting frame for the vat, and mechanisms for transmitting motionfrom said motor to the reciprocatory plunger and to the wringer, the entire combination constituting a unitary machine.

The main object of my present invention is to increase the general working efficiency of the various parts of a washing machine of this type by providing the vat with a perforated false bottom a sufficient distance above the bottom of the vat to form amintervening chamber to permit the washing fluid and air to be forced by suction and pressure entirely through the clothes from the bottom upward and from the,top downward during the operation of the inverted cupshaped-dashers, and to thereby produce a more effective and expeditious cleansing of the clothes and at the same time greatly increasing the output without adding materially to the expense of the entire apparatus.

Second, to establish a more direct drive between the motor and dasher operating mechanism and also between the motor and wringer operating mechanism.

Third. to surround the guide post for the plunger by a rotary sleeve which may be rotated by the clothes if they become wound around the same by the intermittant rotary motion of the dashers thereby reducing to a minimum the liability of mutilation of the.

clothes during the washing operation.

Fourth, to construct the yoke which connects the dashers to the plunger in such Y manner that it will better resist the strain to which it is subjected without liability of bending or springing and to thereby produce a more eifective pressure upon the clothes during the compression stroke of the dash'ers.

Fifth, by yieldingly supporting the dashers upon the yoke in such manner that the connections are substantially concealed and at the same time to enable the dashers to be easily and rguickly removed from the yoke when desire Sixth, to enable the yoke to be easily and of the legs of the tripod in such manner that it may be swung to different positions over and away from the top of the vat ithout liability of over-turning the machine, hereby avoiding the rise of extra means of support for this purpose.

Ninth, to assemble the various mechanisms upon the machine in such manner as to avoid excessive vibration thereof when in operation.

Tenth, to support the vat on the frame in such manner that it may be readily removed without disturbing any of the other mechanisms except the removal of the yoke with the dashers thereon and the post.

Other objects and uses relating to other specific parts of the machine will be brought out in the following description.

Figs. 13 and 14 are enlarged sectional views taken respectively on lines 13-13 and l t-1Q, Fig. 2.

Figs. 15 and 16 are enlarged detailed sectional views of one of the casters and its connections with one of the legs of the vatsupporting frame.

The machine, as illustrated, comprises a main supporting frame -lhaving a circular platform disposed in a substantially horizor plane and supported by a series, of, in thisinstance, three'upright legs -3- in uniformly spaced relation circumferentially,.said legs being extended some distance above and below the plane of the platform -2-, and are secured to said plat- A. circular band or ring -5- is secured by bolts -6- to the inner faces of the upper ends of the legs -3- to assist the platform ---2- in holdin the legs in fixed relation to each other and to saidplatform, said of channel irons with their channels 'facin inwardly for imparting additional rigi ity and strength thereto.

The upper ends of the inwardly projectin ribs of the le s -3- are recessed at to-form shou ders .-8- which are engaged by the lower edges of the ring pr to further stifi'en the frame a ainst torsional strains and at the same,

b I time affording a more positive connection between the band -5- and legs.

' The lower ends of the legs are mounted upon suitable casters -9- each of which comprises a bracket -10- a roller support ing frame -11- having a spindle -12- secured thereto and jo-urnaled in a socket -.-13- in the bracket -10- and'a roller -14- journaled on the caster frame -11-. The bracket -10- is provided in one side with a vertical groove -1.5- TOI,;I.Cel/Tlng the adjacent portion ofthe leg -3- and is secured to said leg by bolts -16- and -17-, one of which, as. -16-, is of sufficient length to enter an annular groove -.-18- in the upper end of the spindle -12-to hold the latter in operative position in the socket -13- and at the same time allow itto turn freely in said bracket, the other bolt-l7- being screw threaded into the bracket to more firmly secure. it to the leg.

The lower end of each bracket is provided with a laterally projecting shoulder -19- at the lower end of the grooves -15- to form an abutment for the adjacent end of the leg -3-, thereby relieving the strain upon the bolts -16- and -17- and transmitting it directly to the bracket and casters.

A circular vat -20-i.s supported directly upon the platform -2- within the legs -3- and ring or band -5- so that it may be readily removedby upward displacement and is provided with a suitable lid or cover -2-1- loosely resting upon its upper edge.

The major portion of the vat is preferably made of non-corrodible sheet metal but in of the interior mechanism may be inspected from time .to time, one side of the vat is pro vided with a transparent panel '-22- of lass or other suitable material made to conorm to the curvature of the main body and has, its edges suitably held against the inso order that the washing operation and action 1 nor faces of the marginal edges of the opening by internal flanges -23- which may be brazed or otherwise secured tothe main body of the vat around the edges ofthe opening in which the glass panel -22- is inserted. The cover or lid -21- is also provided with a central circular panel -24:- of glass or other transparent material suitably held against the inner face of the metallic portion of the cover by flanges -25- which-are clamped to the ietallic portion by bolts or screws -26-, Fig. 2.

A tubular post -27- is secured at its lower end in re istering openings 28- to the center of t e platform. -2- and the bottom of the vat -20- and rises-some distance above the bottom of said vat for receiving and guiding a vertically movable plunger -29- hereinafter described, said post being provided near its lower end with an annular flange -30- resting upon the upper face of the bottom of the vat and is also provided with a reduced nipple -31- extending through the registering openings -28- and having its lower end threaded and engaged by a nut -32- which is tightened against the underside of the adjacent portion of the platform -2- to firmly hold the post in operative position and at the same time permitting it to be easily and quickly removed if it is necessary, by simply removing the nut -32-. 1

The upper end of the post -27-' is also of the post or just above the flange downward, w

the upper end of said sleeve being crimped or turned inwardly to form an annular flange -37- which rests upon the shoulder 34.

The reduced upper end of the nut --33--- is provided with-an annular groove -38 for receiving a split ring-3&- which serves to hold the sleeye against upward displacement and also permitsthe sleeve to be easily and uickly removed by simply springing the sp 't ring -39 out of place whereupon the sleeve may be detached by upward displacement.

A. perforated sheet metal plate 40 of substantially the same diameter as that of the interior of the vat is supported in said vat a short distance above and in fixed relation to the bottom thereof by means of suitable feet or projections 41- on the lower side of the plate, which is provided with a series of perforations -42-.

This perforated plate constitutes what may be termed a false bottom. having its central portion provided with an opening for receivin the post -27 and sleeve 35 and a lowin the said central portion to rest upon the base of the post, which additionally holds it in spaced relation to the bottom of the vat.

The object of this perforated plate is to allow the water to pass therethrough from the bottom- 11 ward and also from the to liich permits the clothes which rest thereon to be more thoroughly washed by the vertical reciprocatory dashers by reason of the fact that the water is free to pass entirely through the clothes in reverse directions as produced by the suction and pressure of the dasher cups hereinafter more fully described. I A

The plunger 29 is preferably tubular and extends entirely through and beyond the ends of the post 27 in which it is guided in its vertical movement.

A yoke 43-- 's adjustably mounted upon the upper end of the plunger 29- and is held in its adjusted position by a removable locking bolt I 44- which is adapted to enter in one of the series of openings 4-.5- one above the other in the lun. or some distance above the u er end P 1% PP of the post 27- for supporting the dashers at difierent heights relative to said post or rather relative to the bottom of the vet,

said locking bolt being held in its locking position by gneans of a spring 4c6- which is pivoted at 1-7 to the yoke some distance to one side of the plunger so that the spring 46 may be moved into and out of engagement with the adjacent end of the locking bolt 4A for permitting the insertion and removal thereof into and from the apertures and similar apertures r5' in the hub of the yoke,

This yoke is pi ovided with opposite downwardly curved arms asto better resist the upward thrust strains to which the outer ends thereof carrying the dashers are subjected, particularly when said dashers are brought downwardly with considerable force on the clothes lying on the perforated plate 4=0-.

These arms 48 are of substantially equal length and are provided at their outer ends with tubular heads 49 open at the bottom for receiving the reduced ends or hubs -50 of a pair of dashers 51 These dashers -5l are preferably made in the form of inverted cups or segments of spherical shells 51-, the central portions of which are clamped betweenthe flanged lower end 52 of the stem 5() and a washer -53- which together with the seg ment -5l' and base -52 of the stem -50-- are provided with central registering apertures for receiving a clamping bolt 54- which extends entirely through the stem f 0- and head -49 of the yoke -i3 and is provided with nuts 55 and -5G engaging respectively the lower face of the washer -53 and the upper face of the head -49 of the oke 43, the upper face of said head eing recessed at -57 to receive the nut -56 and thereby conceal the major portion thereof.

The head i9- and stem 50 of the dasher 51 are tubular and telescope one within the other. The inner end of the opening in the stem 50 and outer end of the opening in the head l9 being reduced in diameter to form shoulders 58- and -59 respectively.

A coil spring -60- surrounds the bolt -54iwithin the tubular stem 50- and head 4:9 and has its opposite ends engaged respectively with the shoulders -58 and -59 to exert downward pressure upon the dasher 51T- and also to allow said dashcr to yield vertically under pressure upon the clothes when drawn downwardly by the plunger 29- thereby allowing the plunger to move through its entire stroke.

without liability of overstraining any of the parts.

The connections between each dasher and yoke are identical and, therefore, the description given for one serves to define the other.

Plunger reciprocating mechanism.

A collar -61- is loosely mounted upon. the-lower. end of the plunger "29 andls held against endwise movement relative to said plunger by means of a Washer 62 and a ratchet wheel -63-, the washer being secured to the lower end face of the plunger by means of a screw --6land is engaged with the lower face ofthe collar --6l while the ratchet wheel -63- is secured by-a pin '65 to the plunger and engages the upper end face of the collar.

This collar is provided with pendent apertured lugs -66 for receiving a pivotal pin -67- which projects beyond the outer faces of the lugs for receiving and supporting a pair of links 68, the latter being held in place by cotter pins 69- to permit the parts to be readily detached when necessary.

These links -68 extend downwardly from the pivotal pin 67 and areconnected intermediate their ends by a web -70- preferably integral therewith, .the

lower ends of said links being apertured to receive and support a pivotal pin --7l having cotter keys 72-- to hold it against endwise displacement and permit it to be easily and'quickly removed when necessary.

' Theipin -71 is mounted upon one end of a vertically movable rocking lever -73- having its opposite end pivoted at 74- to a bracket 75 which is secured to the under side of the platform or vat supporting bed -2 said lever having its intermediate portion connected by a pitman --76- to a crank arm -77 on one end of a rotary shaft section 78- having its axis disposed at right angles to-the plane of movement of the lever 73-, as shown more clearly in Fi s. 2, 3 and 5.

his shaft section -78- is loosely journ'aled in one end of a revoluble sleeve or tubular counter shaft -7 9- which is journaled in bearings --80- and 81- formin parts of separate gear cases 82- an 83 both of which are secured to the underside of the bed plate or platform -2- as shown more clearly in Fig. 5, said shaft section 78-- being provided with an annular groove -84-- for receiving a pair of diametrically opposite retainers -85 which are secured by screws 86-- to the adjacent sides of the sleeve or counter shaft is provided with a clutch face -87- cooperating with a companion clutch face -'8S on. the adjacent end of a clutch section -89- within the sleeve 79-, the intermediate portion of said clutch section.

89- being provided with a diametriea-l slot -9()-- therethrough for receiving a key or pin -9lwhich is secured to the opposite walls of the sleeve --79-- and serves to transmit rotary motion from said sleeve to the clutch section 89- and to allow the clutch section to be moved axially within the sleeve for engaging and disengaging its clutch face 88- with and from the companion clutch face -87 of the shaft section -78.

A spindle 92- coaxial with the sleeve -79- is loosely jour ialed at one end in a bushing ,-'93-- in'the outer end of the clutch section -89-- and extends outvwardly through a gear -9-l-- on the outer tion and spindle against relative endwise movement and at the same time pernaittin relative rotation of the clutch section an spindle.

The outer end of the spindle -92- is provided with -a grooved collar 97- for engagement by a shifting arm -98- which is secured to drool; shaft -99' in the gean case --83-, one end of said rock shaft being extended through asuitable opening in the gear case and is-secure'd to a hand ever -100-, by which the shifting member 9S may be rocked in reverse directions for throwing the clutch section -89 into and out of engagement with the shaft sec tion -78 to start and stop the reciprocation of the plunger -Q9 carrying the dashers --5l. v

The means for transmitting motion to the counter shaft or sleeve .79- comprises an electric motor A- havingits frame suitably'secured'to the underside of the bed plate or platform -2 and having its motor shaft as -/I disposed horizontally at right angles to the axis of the counter shaft -79- as shown more clearly in Fig.

3, said motor shaft being preferably made in sections coupled together by a universal joint ato compensate for any slight variations in the alignment of the shaft sections.

A. worm -B- is secured toa motor shaft section -bwhich is journaled in suitable bearings --bin the gear case 8Q and is'connected by a universal coupling -0- to a loose disc or collar --con the adjacentend of a coaxial motor shaft section.

The disc cwhich is loose on the shaft section v0 is connected by a slip clutch D; to the shaft section -c'' to prevent stalling of'the meter in case the load driven by the worm B-- should be excessive, said slip clutch comprising a disc-#1- secured by a pin -din spaced relation to the macaw disc c to receive between said discs 21. fibre disc d Additional discs -e are loosely mounted upon the shaft section e between the 'disrfd and adjacent end'of a coil spring -E-- whichsurrounds the shaft section 0- and has its outer end abutting against an adjusting screw or nut -ewhich is loose on the shaft section -0 and is screwed into the adjacent end of an enclosingsleeve E to adjust the tension'of the spring and thereby regulate the friction between the several discs, the inner end of the sleeve -F- being rigidly secured to the disc -0.

The worm B meshes with a worm gear -f which is secured by a set screw fto the periphery of the sleeveor; countershaft 79- between the opposite end walls of the gear case 82- as shown in Fig. 5, the gear f-- coacting withthe inner ends of the bearings -80 to hold the sleeve 79- against endwise movement.

It is now clear that when the motor is in operation and the clutch section 89- is forced into engagement with the clutch face -87 of the crank shaft -78 reciprocatory motion'will be transmitted to the plunger 29 through the medium of the pitman 76, lever 73-, link -68- and collar 61 for operating the dashers -51 into and out of engagement with the clothes which may rest 11 on the perforated plate 40 near theli vat.

Intermittent rotary motion.

Suitable means is provided for intermittingly rotating the, plunger and dashers thereon step by step in one and the same direction as the plunger is elevated, and for this purpose is provided the ratchet wheel 63- secured to the lower end of the plunger, in the manner previously described, directly above the collar A61- which has its upper end reduced in diameter' to form a journal bearing for a horizontal rocking member G carrying a pawl -g and a radial pin g, the pawl -gbeing spring pressed radiallyinto engagement with the teeth of the ratchet wheel 63 to rotate the plunger one or more -tooth spaces at a time when the lever G- is rocked in one direction and to permit said pawl to return freely across the face of the teeth.

A plate H is secured to the underside of the bed plate or platform -2 and extends downwardly therefrom, said plate being provided with a diagonal slot having its opposite walls forming cams -h and h, the lower end of the slot being open and disposed in the path of the vertically movable pin to receive said pin as the plunger approaches the limit of its upottom of the ward movement and to pemit it to ride against the cam face -hfor rocking the member-.-G+ and pawl carried thereby for rotating the plunger with the dashers thereon through a limited are as the pin continues its upward movement along the cam face k, the opposite cam face hserving to return the rocking member -G to its starting position as the plunger is moved downwardly during which latter operation' the pawl slides freely across the face of the teeth of the ratchet wheel 63-.

The lower end of the slot in the plate -H- is flared circumferentially to assure the entrance of the pin --g-- into said slot when the plunger is elevated.

Wri'nger mechanism.

' end of the vat -20- and comprises a frame iand a pair of rollers i which are adapted to be rotated in reverse directions for feeding the clothes into and out of the vat.

The wringer frame --c'-is provided at one end with a gear case J- having a hub mounted upon the upper end of a stationary supprorting post -j'-, as shown in Figs. 6 an the lower end of said post being removably mounted on a tubular hub 83 of the gear case 83-.

The wringerframe is preferably made in sections, one section carrying t e rollers -iwhile the other section is removably mounted upon the upper end of the post by upward displacement, the sections of the wringer being secured together end to e d by bolts he upper portion of the post j just below the hub jmay be attached to the circular band -5-- or adjacent leg-3- by means of a bracket -K-, which together with the hearing at the lower endof the post serves to hold it rigidly inan upright position, it being held against rotation by any suitable means, as, for example, a clamping plate -lc-- on the bracket -K-.

The portion of the 0st jwithin the hub j is provide with a series of, in this instance, four radial apertures -k-- arranged equal distances apart circumferentially for receiving a locking bolt L-- which is slidable radially in a socket and in one side of the hub -y'-- and is spring pressed inwardly into the aperture k which may register therewith to hold the wringer in its adjusted position, the outer end of the pawl or bolt being provided with a handle "or knob M by which it may be withdrawn outwardly against the action of its retracting spring to release the wringer frame and to allow it to be turned horizontally about the axis of the post y"- to and Eli journaled ina' hearing 83 in the gear case 83- and its upper. end journaled in bearings --n in the lower and upper side of the gear case-wi the lower end of said shaft being provided with a gear -O- meshing with the gear --9 lon the countershaft -79-- A pair of beveled gears 0 are loosely mounted upon the upper end of the shaft N- within the-gear case -J- and are normally engaged with the lower and upper faces of the gear n.

The inner ends of the beveled gears --0- are provided with clutch faces '0- adapted to be engaged by correspondin clutch faces on the ends of an interposed clutch collar -P- which is splined upon the shaft --N- to rotate therewith and to move endwise into and out of engagementhwith the clutch faces o-.

A. rock shaft --Q is journaled in a suitable bearing R- on the outer end of the gear case -J- and is held against endwise movement by an adjusting screw 4 which is engaged in a radial threaded aperture in the bearing -R and enters an annular groove rto hold the rock shaft --Q; is provided with an eccentric pin S carrying the roller -e-- which rides in the annular groove in the collar --P. to

adjust said collar axially into and out of i engagement with one or the other of the gears 0- according to the direction in which it is desired to rotate the wringer rolls, said rock shaft being provided with a hand piece -:gby which t may be oper-' ated.

Operatimz.

The operation briefly described is as follows. Assuming that the motor is in operation, power may be transmitted to the plunger-for reciprocating the dashers -51- vertically by simply throwing the clutch 88- to locking engagement with the com- 4 panion clutch -87- by means of the hand lever 100--.

- This operation may be efiected without operating the wringer mechanism, which on the other hand may be operated in either direction independently ofthe plun er by simply shifting the clutch member in one direction :or the other according to the direction in which it is desired to rotate the :ment of both wringer foils, in which case the clutch --88 wouldbe withdrawn from engagement with its companion clutch 87. Or, .if desired, both the lunger and the .wringermechanism'may be rought into action simultaneously by the proper adjustof the clutches -88 and The operations and functions of the various other parts have been clearly defined in" the foregoing-description and While the construction shown is particularly simple, eilicient and economic'ahll do not Wish to limit myself to that specific construction.
